New England Distribution

Non-native: introduced
(intentionally or
unintentionally); has become naturalized.

County documented: documented
to exist in the county by
evidence (herbarium specimen, photograph). Also covers
those considered historical (not seen in 20 years).

State documented: never been
documented from the
county, but known from the state. May be present. Or,
may be restricted to a small area or a habitat (alpine,
marsh, etc.), so unlikely found in some
counties.

Note: when native and non-native
populations both exist in a county, only native status
is shown on the map.

Facts About

Hieracium kalmii was named for Pehr Kalm (1715-1779), a Swedish botanist who spent time in America and has several other species bearing his name (for example Lobelia kalmia and Hypericum kalmianum). The Ojibwa nibbled the root for luck in hunting, to attract a doe.

Sometimes Confused With

flower head stalks with abundant stipitate glands and leaf blades entire or with minute teeth (vs. H. kalmii, with flower head stalks with few or no stipitate glands and leaf blades evidently toothed).

leaf blades linear to lanceolate or narrow-oblong, the principal ones mostly 3–15 mm wide, mostly 4–12 times as long as wide, provided with abundant stout, rigid, conical hairs, at least toward the margin of the blade (vs. H. kalmii, with leaf blades lanceolate to oblong-lanceolate or narrow-ovate, the principal ones mostly 12–40 mm wide, mostly 2–5 times as long as wide, lacking rigid, conical hairs or these very sparse).

Lepage is an extremely rare hawkweed hybrid in New England. In general aspect it resembles
H. kalmii but without large leaf blade teeth (which are sometimes present in
H. kalmii) and with some of the peduncles of the plant bearing 1 or a few stipitate glands.
